Ah..ok. Well, RAML 1.0 has a few big additions that may take some time to get raml2html 1.0 fully supported. I believe @Mike_Stowe and a few others are working on it as the 1.0 spec nears completion. I suspect it will be some months before it is ready though, but rest assured it is in the works.
RAML 1.0 with annotations and YAML types is going to be interesting to see what unfolds in the community as well. With annotations, you could add all sorts of cool capabilities, but the parsers for things like docs, sdks, etc will have to be aware of specific annotations and their definitions in order to utilize them in generated output. For example, the Try it now feature, which I am not a fan of, could be greatly enhanced by adding an annotation that can indicate a request chain to call that would retrieve the data that might be needed for the try it now request. Postman makes this pretty easy with its collections, but Try it now requires some copy/paste usually from previous requests (possibly) to work. A parser that could utilize annotation data to figure out the 1 or more requests needed to pull results from to feed the try it now request about to be made would make it easier to use the feature in HATEOAS like APIs. HATEOAS is another area annotations might be able to be used, to name a couple.
